I actually never gave it a second thought by showing the controls by the default equipment, as it currently only shows for new items, figured it was probably natural by then, so nice catch!
It's pretty broad what can be seen as "more options". Music and sound volume is understandable. But more options also require more effort to implement them. Fullscreen does come in mind though.
It's quite the game essense of a Metroidvania (especially in the Metroid games) to figure out and discover where to go, I didn't wanted to give too many hints, as the map does feel pretty small.
But I had once a hint system in mind, so I might pick that up again.
Once again, thanks for playing my game, it's been a while since I've recieved feedback of it, so it's greatly appreciated!
I'll give the feedback a thought the next time I'll work on the update again.
